You were between the two of them, Rider and Assassin. They were… hardly normal Heroic Spirits confined to Servant containers, though. Rider's ability belied his apparent age to the point you had to wonder just how strong he really was, and that spear narrowed his identity down to a very short list.
And Assassin, Assassin was something else, a trickster who hid his identity behind the legends of other spirits. I gripped my sword tighter, glancing between the two of them.
The clash here could end in a casualty, and it would be to my advantage if it was Assassin, yet…
Illya should have been here by now.
I took one step, then two, backwards.
"I take my leave then, Rider." I state clearly. "Your Master's protection is a matter for you now."
He glances at me, almost bored, his spear held lazily and pointing at the ground.
"I guess so, Saber."
I almost think to try to mislead him, but then I realise that Shirou was a Master, and more notably, right there. Any attempt was doomed to fail the second he checked the Book of Masters, if it was not already doomed.
Ha. I knew that I'd never maintain the deception anyway. It was a nice thought, to think I might be able to, but I knew it was a pipe dream.
"Saber, help me." Assassin whispered urgently, though he made no attempt to keep his voice low enough that Rider couldn't hear. "We can take him together. One less Servant in the war puts us both a step closer to winning."
"Ha. Why would she help you, grovelling coward?" Rider growled. "Attacking a Master before they'd summoned forth a Servant. Where's your fighting spirit!? You do nothing but show that your class aptly describes you, coward!" The spear came up lazily, pointing at Assassin's chest.
"Tch. Great, another blood thirsty bastard. How dull." Assassin shot back, readying his blades.
"Cursed to loneliness, on this path of steel."
And then he shot off. I blinked. His movements were much more sure now. As if he really intended to take on Rider, win, and then kill Shirou, yet…
His class really should be too much of a hindrance to do that. Does he really believe he could defeat Rider? In my experience, there was no such thing as an Assassin who could take another heroic spirit in a head on fight, yet…
He was not a Hassan, though. The tattered Holy Shroud made that abundantly clear…
Yet that wasn't my concern. I took one step, then two, backwards as the Assassin lunged forward. Rider didn't move until the last second, yet when he did, his spear turned into a blur of red, leaving a ribbon of crimson in its wake.
*Smack* *Clang*
He was fast. Very fast. The exchange between the two, swords and spear blurring as they moved, was amazing, a lethal dance, yet…
I tore my eyes away, turned on my heel, and ran back into the house.
'Illya?'
I called out in my mind, yet I expected no answer. While the bond could go two ways, I had no way of initiating such a thing myself. The house was in tatters, yet there was no sign of Illya as I moved. I could only presume she was back near the entrance, but…
My movements didn't slow. If anything, they quickened, my mana leaving cracks in the floor as I moved.
"Illya!"
I called out to her. My breathing was rapid, yet as I reached the gate, there was no-
"I'm here."
She sounded shaky, squeaky even. My gaze fell down to her. It took a moment to find where, exactly, she'd taken cover, a small alcove in the wall.
I let out a small sigh of relief, taking a step towards her. She shivered, standing up.
"Careful. Archer is still here."
What?
I froze. Archer was still here? But the Archer was Assassin, wasn't it?
"Where?"
It was as if a beat passed, spinning on my heel and swinging my sword. The javelin smashed into the ground next to me.
No, not a javelin. A sword.
…
Assassin had been shooting swords at us?
Yet these ones had none of the precision and accuracy of the ones before. It was as if…
"The Master has taken over." Illya finished my thought for me. "Right?"
"Likely. It wasn't Archer, but Assassin." I answered. "Clearly Assassin lent out his bow."
"But for a human to fire that far?"
"If they were firing from a bow on the level of a Noble Phantasm, it wouldn't be hard." I noted. "The only difficulty would be accuracy..."
Just how was the Master shooting with any sort of accuracy? How far away was the Master?
It was as if a half-dozen questions lit up in my mind. It was… puzzling, to say the least.
"The Zelle barely held out." Illya noted, raising a piece of her hair where the strands had unravelled. "They're… powerful mysteries. Strong enough that simply using more mana isn't really enough to-"
"They're degraded Noble Phantasms, I think." I muttered. "Images of legendary weapons used to hide Assassin's true identity. It would appear that his parlour trick holds just a little power."
*Boom*
Both of us winced at the sound of earth tearing. It seemed like Rider and Assassin were well and truly going at it.
"Should we retreat?" Illya asked. I frowned.
"We've come so far though?"
"Emiya's house is in ruins, and there's no way to put ourselves forth as just a ally with another Master shooting into the area." Illya reasoned. "And you aren't going to drag him with us."
That was true, yet… if I could get Illya near Shirou, maybe, just maybe, they could bond in camaraderie while I join Rider in removing us of our pest.
Yet… if Shirou found out he had Avalon…
Now that he had Rider, his Servant would be very much against the idea of surrendering the sheathe. We may well have lost our chance completely. Everything relied on us convincing Rider to hand us back Avalon, and there was no-
"Ansuz."
What?
*KABOOM*
"… oh… Rider knows Magecraft..." I note dumbly, just blinking at the huge cloud trailing from the other side of house. Illya didn't respond for a while, just breathing next to me.
*Smash*
I bat aside another sword. This one is quite sloppily aimed. I'm not sure it would have gotten past my armour, but I wasn't about to find out.
"Saber!"
No, I would have to decide now. If Assassin was busy, then this was quite literally the best time to run. We might even be able to kill the Master. Yet if we leave…
We might just lose Avalon…
I…
